Abstract

The invention provides a communication waveform comprehensive transmission performance evaluation method and system. The method comprises the following steps: a system classification step: classifyinga communication waveform efficiency evaluation system; a performance index simulation step: setting a transmission waveform and parameters, setting a simulation scene, and simulating each waveform performance index; an efficiency evaluation step: evaluating the comprehensive efficiency of the waveform by using a TOPSIS method; and a waveform index evaluation step: evaluating the waveform index byusing the gray hierarchical model. According to the invention, transmission effectiveness, resource effectiveness and anti-interception indexes of waveform indexes are simulated, a TOPSIS method is used, the waveform is comprehensively evaluated by adopting a gray multi-level evaluation method and a fuzzy neural network evaluation method, and the three evaluation means are unified by using the algorithm, so that the defects that the TOPSIS method is not easy to meet the actual demand, the gray multi-level evaluation method is too subjective and the fuzzy neural network is easy to overfit areavoided, and the evaluation system meets the user demand and has generalization ability.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for evaluating comprehensive transmission performance of communication waveforms. Background technique [0002] With the development of wireless communication technology, the application scenarios are constantly enriched, and there are more and more waveform systems. How to choose the appropriate waveform for different needs is an urgent problem to be solved. The comprehensive transmission performance evaluation of communication waveforms can provide a basis for quantitative analysis for software radio system waveform selection, so as to rationally allocate communication resources according to war requirements. [0003] Most of the existing waveform performance evaluation methods are based on fixed communication waveform parameters and use a single target as the evaluation method, which has certain limitations. For example, there are li...
